On the 25th of July `09, we have been visited by semashur or Sekolah Menengah Sains Hulu Selangor. All of them are from the Board Of Prefects and the main objective is to exchange information with the SDAR Prefect Board. They visited the Academic block as well as the hostels. They were very impressed with the modern buildings of sdar as well as the breathtaking landscape.

On the 15th of July 2009 there was a kite flying competition organized by Kelab Pelancongan dan Pencinta Alam. It was really fun and enjoying activity as there`s no such activity held before. Some of the participants managed to get their kite flying high while some were just playing on the ground. Congratulation to the winners and to others, try your best in the next kite flying competition.

Prototype Nokia phone recharges without wires

Pardon the cliche, but it's one of the holiest of Holy Grails of technology: Wireless power. And while early lab experiments have been able to "beam" electricity a few feet to power a light bulb, the day when our laptops and cell phones can charge without having to plug them in to a wall socket still seems decades in the future.

Nokia, however, has taken another baby step in that direction with the invention of a cell phone that recharges itself using a unique system: It harvests ambient radio waves from the air, and turns that energy into usable power. Enough, at least, to keep a cell phone from running out of juice.

While "traditional" (if there is such a thing) wireless power systems are specifically designed with a transmitter and receiver in mind, Nokia's system isn't finicky about where it gets its wireless waves. TV, radio, other mobile phone systems -- all of this stuff just bounces around the air and most of it is wasted, absorbed into the environment or scattered into the ether. Nokia picks up all the bits and pieces of these waves and uses the collected electromagnetic energy to create electrical current, then uses that to recharge the phone's battery. A huge range of frequencies can be utilized by the system (there's no other way, really, as the energy in any given wave is infinitesimal). It's the same idea that Tesla was exploring 100 years ago, just on a tiny scale.

Mind you, harvesting ambient electromagnetic energy is never going to offer enough electricity to power your whole house or office, but it just might be enough to keep a cell phone alive and kicking. Currently Nokia is able to harvest all of 5 milliwatts from the air; the goal is to increase that to 20 milliwatts in the short term and 50 milliwatts down the line. That wouldn't be enough to keep the phone alive during an active call, but would be enough to slowly recharge the cell phone battery while it's in standby mode, theoretically offering infinite power -- provided you're not stuck deep underground where radio waves can't penetrate.

Nokia says it hopes to commercialize the technology in three to five years.

This photography competition is to enhance the students skill on photography held through out april. Congrats to Nor Ayman for his creative photography artwork and to Hazim for his artwork(its cool but doesn`t based on the theme...hehe). To others, dont give up. The competition still on for the theme anger
